The SZSMF4L series is designed to protect sensitive systems or components from high voltage, high energy transients. It offers a fast response time, low zener impedance, high surge and excellent clamping capabilities. Because of its small size, it is ideal for use in automotive electronics applications.

Features

Zener transient overvoltage suppressors
Working peak reverse voltage range 5 V to 78 V for unidirectional and 10 V to 78 V for bi-directional
Peak power: 400 watts &commat; 1 ms
Planar chip design with low leakage current performance
Response time is typically < 1 ns
ESD rating of class 3 (> 16 kV) per human body model
IEC-61000-4-2 ESD 30 kV(Air), 30 kV (Contact)
Lead orientation in tape: cathode lead to sprocket holes
These components are Pb-free and are RoHS compliant
SZ prefix for automotive and other applications requiring control change requirements; AEC−Q101 qualified and PPAP capable

Applications

TVS components are ideal for the protection of I/O Interfaces, VCC bus and other vulnerable circuits used in Automotive applications.
